You are going to make some new, more detailed textures right?

Very nice. Very evil looking. But for some reason the coat seems just a bit off. Don't know why. Maybe make the green and white not contrast so much. Make them a bit more muted. Aside from that, however, the model is great!

I just had a thought, though I have no idea if it is possible... I wonder if you could make it so the weapon upgrade (silencer, laser sight etc.) would show up on the model in first person view.
